The concept of the Iron Triangle of Health Care was first introduced in William Kissick’s book, Medicine’s Dilemmas: Infinite Needs Versus Finite Resources in 1994, describing three competing health care issues: access, quality, and cost containment. [1] [2] Each of the vertices represents identical priorities. Increasing or decreasing one ...
The slider-crank linkage (RRRP) is one type of arrangement such that one link is a crank, which is then connected to a slider by a connecting rod. The inverted slider-crank is another type of arrangement such that there are two cranks with a slider acting as the coupler. Examples of 3R1P linkages include:
The second edition of the book where the model's application was expanded from PRECEDE to PROCEED with the addition of the policy, regulatory, and organizational aspects of planning for environmental changes that took health promotion beyond a narrower understanding of health education; Green L, Kreuter M. (1999).
An arc-based single dwell linkage uses the approximation of a circular arc. The concept for linkage dwell mechanisms is that a node located at the center of the circular arc segment of a coupler curve will remain relatively stationary. This is achieved first by choosing a desired coupler curve created by a four-bar linkage. Once a coupler curve ...
The Scott Russell linkage (1803) translates linear motion through a right angle, but is not a straight line mechanism in itself. The Grasshopper beam/Evans linkage, an approximate straight line linkage, and the Bricard linkage, an exact straight line linkage, share similarities with the Scott Russell linkage and the Trammel of Archimedes.
In kinematics, a five-bar linkage is a mechanism with two degrees of freedom that is constructed from five links that are connected together in a closed chain. All links are connected to each other by five joints in series forming a loop. One of the links is the ground or base. [1]
As in the case of the Sarrus linkage, it is a particular set of dimensions that makes the Bennett linkage movable. [3] [4] The dimensional constraints that makes Bennett's linkage movable are the following. Let us number the links in order that links with consecutive index are joined (first and fourth links are also joined).
First Lady Hillary Clinton at her presentation on health care in September 1993. According to an address to Congress by then-President Bill Clinton on September 22, 1993, the proposed bill would provide a "health care security card" to every citizen that would irrevocably entitle them to medical treatment and preventative services, including for pre-existing conditions.
